Question:
Honorable Shaykh, may Allah grant you success. The questioner says: I forgot to recite Surat al-Fatihah in one of the obligatory prayers. Do I have to repeat this prayer?
Answer:
If you were behind the imam, the imam’s recitation is sufficient. However, if you were praying alone, you must repeat the prayer. If you remember this shortly after, you stand and perform a rak'ah, then prostrate for forgetfulness. But if a long time has passed or your wudu' has been broken, you must repeat the prayer from the beginning. Yes.
